Trend Scalper TR
Trend Scalper TR — a MetaTrader 4 expert advisor (trading robot) kept in the Old Kings collection. Judging by its name, it is built around short scalping trades and following the trend.

It has 13 settings, for example Lots If No MM (default 0.1), Stoploss (default 40) and Take Profit (default 999). Watch it on a demo account for a while — robots can behave differently with each broker. Inside: 1 EA file with source code (.mq4) you can open and edit in MetaEditor.
